toxic relationship

hi so i’ve been with this boy for almost a year now (well i wouldn’t say we’re dating since he never said we were but never said we weren’t if you know what i mean) anyways, he yells at me, calls me the worst names, blocks me and unblocks me, tells me he hates me but then says he loves me, tells me to leave him alone but gets mad when i don’t talk to him, i just don’t know what to do. i mean i love this boy with my whole entire heart, but i hate when he treats me so bad. i want him to change so bad and i keep thinking he will.
